My friend asked me for n Uno cards' box, but I only had the worst spool of filament in the entire world. What do you do?

This cards box prints in as little as 3h total (1.5h bottom + 1.5h top), the whole body has no retraction, a fixed feed rate and no seem. it should work even using the worst filament in the world (and it did!).

I also included the original sldprt because on this basic principle you have quit a lot of gesign freedom.

Enjoy!
